How the 61832 model number is decoded
In the 61800-series (diameter series 8 of ISO 15) the last two digits encode the bore: 61832 carries bore code 32 = 160 mm. Outside diameter 200 mm and width 20 mm come from the ISO 15 boundary-dimensions general plan. With no seal suffix the bearing is open: no shields or seals are fitted and lubrication is supplied by the application. For normal-load mounting with a rotating inner ring on a 160 mm shaft, typical catalogue practice is a m6 shaft seat with an H7 housing bore — verify against the actual load direction and magnitude. In the SKF catalogue this open execution carries the bare designation; protected variants are ordered separately as -2Z and -2RSH.
Typical equipment & failure modes
Common applications
- textile machinery
- packaging machinery
- space-constrained gearboxes
- clutch and transmission assemblies
Known failure patterns
- contamination wear from dust and dirt ingress through the open arrangement
- lubricant starvation when no regreasing interval is maintained
- cage damage from operation beyond the limiting speed
- electrical pitting in VFD-driven motors without grounding protection
Selection pitfalls — read before you substitute
- Mount this 160 mm bore bearing by heating the inner ring (induction heater, max 120 °C) — never drive it home through the outer ring or balls, that brinells the raceways.
- The 618xx thin section at 160 mm bore has only a 20.0 mm radial section height: it saves space but is highly sensitive to misalignment, shaft deflection and shock loads — verify shaft stiffness before choosing it over a 6232.
- The open 61832 has no lubricant retention: grease escapes and contaminants migrate straight into the 160×200×20 mm raceway, so specify a sealed arrangement for dusty or washdown duty.
- Open bearings tolerate the highest speeds in the 61800-series but need a defined regreasing interval; run-to-failure lubrication is the dominant cause of early failure in open 61832 units.
- The housing bore for the 200 mm OD should be round within IT7; an oval bore pinches the outer ring of 61832 and shows up later as two-point loaded raceway wear.
- Deep-groove ball bearings tolerate only minutes of misalignment; if the 200 mm housing cannot be aligned, switch to a self-aligning type rather than shimming 61832.
- The open 61832 needs external sealing and application-supplied lubrication; in the SKF catalogue the protected variants are separate order numbers 61832-2Z (shields) and 61832-2RSH (contact seals), not suffix-free 61832.
- The 49.4/64 kN ratings here are SKF Explorer-class figures from catalogue PUB BU/P1 17000/1 EN (Oct 2018); SKF can revise internal geometry and ratings without changing the designation, so treat the catalogue version and date as part of the specification and re-verify for critical drives.
Frequently asked questions
What are the dimensions of a 61832 bearing?
A 61832 deep-groove ball bearing has a 160 mm bore, 200 mm outer diameter and 20 mm width (6.299 × 7.874 × 0.787 in), per ISO 15 boundary dimensions. It is an open bearing with no seals or shields.
What internal clearance does 61832 have?
Unless a clearance suffix says otherwise, 61832 is manufactured to normal (CN) radial internal clearance. Tight fits and hot shafts consume clearance in service — for those conditions order the C3 execution of 61832 and verify the residual clearance after mounting.
How should 61832 be mounted?
Apply the mounting force to the ring being fitted: on a 160 mm shaft seat the press load must pass through the inner-ring face only. Induction heating of the inner ring (max 120 °C) is the clean method at this size. Never strike the outer ring, the cage or the seals.
What lubrication does 61832 need?
The open 61832 is lubricated by the application; a NLGI 2 lithium-soap grease filled to roughly 25–35% of the free volume is the common choice, with a defined relubrication interval.
What is the SKF designation and catalogue data for 61832?
In the SKF Rolling Bearings catalogue this size is listed as 61832 — the open (unsealed) execution, 160×200×20 mm per ISO 15. Quoted values: C 49.4 kN, C0 64 kN, Pu 2 kN, limiting speed 4000 r/min, mass 1250 g. Brand suffixes (2Z, 2RSH, 2RSL) differ from the industry-neutral spelling 61832.
